Bare rust project for STM32

Read the Architecture.md document for more information.

Instalations

rustup target add thumbv6m-none-eab
rustup target add thumbv7em-none-eabihf

brew install probe-rs-tools
or
cargo install probe-rs-tools 

Running on Board

Connect up the stlink to board.

make flash

or

cd crates/ui; cargo flash --chip STM32F405RG --bin ui --no-default-features --features bsp/board-hactar12,hal/stm32f405 --target=thumbv7em-none-eabihf

In a separate window, on a mac, can monitor USB console with

screen /dev/tty.usbserial<SOOMETHING> 115200

To exit screen, type ^A^\

Running with GDB

From in the main directory, start

openocd -f crates/ui/openocd.cfg

and leave running. Then in another window do

cd crates/ui; cargo run --bin ui --no-default-features --features bsp/board-hactar12,hal/stm32f405 --target=thumbv7em-none-eabihf

or for the MGMT chip

from in the main directory, start

openocd -f crates/mgmt/openocd.cfg

cd crates/mgmt; cargo run --bin mgmt  --no-default-features --features hal/stm32f072 --target=thumbv6m-none-eabi

this will bring you to gdb prompt where you can type "c" to continue.

Can flash the mgmt chip with (make sure openocd is not running)

cd crates/mgmt; cargo flash --chip STM32F072CB --bin mgmt --no-default-features --features hal/stm32f072 --target=thumbv6m-none-eabi --release

Running on Emulator

Does not work yet.

TBD broken
cargo build --features bsp/board-qemu,exit --target=thumbv7em-none-eabihf 
qemu-system-arm  -S -no-reboot -cpu cortex-m4  -machine netduinoplus2  -gdb tcp::3333  -nographic  -semihosting-config enable=on,target=native -kernel target/thumbv7em-none-eabihf/debug/ui  --trace "memory_region_ops_*" 
arm-none-eabi-gdb -q  target/thumbv7em-none-eabihf/debug/ui --init-eval-command="target extended-remote localhost:3333"

The -S cause the above to wait for the debugger to connect.

Running on the Simulator

make run-sim

Notes

Useful things to look at size of binary:

cd crates/ui
cargo build  --release
arm-none-eabi-size ../../target/thumbv7em-none-eabihf/release/ui 
cargo nm --release -- -a -n

cargo objdump --bin mgmt --no-default-features --features hal/stm32f072 --target=thumbv6m-none-eabi   --  --disassemble-symbols="mgmt::my_main::h198d2405b1d924dc"  --source   --demangle

cargo objdump --bin mgmt --no-default-features --features hal/stm32f072 --target=thumbv6m-none-eabi   --  --disassemble-all  --source   --demangle

 cargo objdump --release  --bin ui --no-default-features --features bsp/board-hactar12,hal/stm32f405 --target=thumbv7em-none-eabihf  --  --disassemble-symbols="ui::fib::fib::h66fa5b0d20d9db18"  --source   --demangle

cargo objdump  --bin ui --no-default-features --features bsp/board-hactar12,hal/stm32f405 --target=thumbv7em-none-eabihf  --  --disassemble-symbols="ui::fib::fib::hc749cb1bc8cd917c"  --source   --demangle
